Wow 20/20 females.. no it wasn't greed that's for sure hah.. I think its your lighting. Your growspace is 4 by 6 so thats 24 square feet... you need to have atleast 8,000 lumens per square foot, your 420 hps is only putting out around 50,000 so your only really covering 6 ft. or 1/4 of your space.. if you want more bud your going to have to think of getting a couple of thousand watters on light movers.. either that or, grow less plants. If you take your time and give 1 plant a nice long veg under your hps then flower you can manage up to a pound if you do it right...
